Items surplus or wanted

I realise this is a big ask, but am a born again believer who is the sole earner and have a family of 4 young children... My car is destined for the scrapyard as is going to cost too much for M.O.T repair; is there anyone who can help me find, or offer to sell me a vehicle very cheaply? Style/age unimportant, so long as it is reliable and very cheap! (hundreds of pounds, not thousands!). Don't mind doing plumbing, gardening or labouring to offset the value of car. I live near Huntly, thanks for reading.
